• Newborn sperm whales are between 3.7 to 4.3 meters (12 to 14 ft) in length. [1] • Sperm whales exhibit a large amount of sexual dimorphism with their size and proportions, with males generally being much larger than females. Female sperm whales are sexually mature at 8 to 9 meters (26 to 30 ft) in length, and physically mature at about 10 ...
The Mysticeti, or baleen whales, have a filter-feeding system, are fifteen species in three families, and include the blue whale, right whales, bowhead whale, humpback whale rorqual, and gray whale. The wide range of body mass in cetaceans has a significant influence on the capacity for oxygen storage and use, which affects dive limits.
The sperm whale or cachalot [a] (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.
Physeter is a genus of toothed whales.There is only one living species in this genus: the sperm whale (Physeter macrocephalus). [2] Some extremely poorly known fossil species have also been assigned to the same genus including Physeter antiquus (5.3–2.6 mya) from the Pliocene of France, [3] and Physeter vetus (2.6 mya – 12 ka) from the Quaternary of the U.S. state of Georgia.

Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
The dwarf sperm whale is a small whale, 2 to 2.7 m (6 ft 7 in to 8 ft 10 in) and 136 to 272 kg (300 to 600 lb), that has a grey coloration, square head, small jaw, and robust body. Its appearance is very similar to the pygmy sperm whale, distinguished mainly by the position of the dorsal fin on the body–nearer the middle in the dwarf sperm ...
The whale was measured at about 44 feet (13 meters) long, roughly the size of a large school bus. It weighs as much as 70,000 pounds (31,700 kilograms), officials said.
